On the other hand, adding an HP modifier seems to not do anything. I don't have much to say besides this as it's not as if it's not doing what it's supposed to, it's simply not doing anything at all. I am on Chrome, using standard 5e character sheets for a homebrew campaign, working off one of my player's sheets while he's helping me try to figure out what's going on, with the HP modiferers.
